Global Warming caused by humans, mabey, probably not.

Before I put up this article, here's a Small piece of my own opinion-Sure we are in a global warming trend, last time I checked we weren't in an Ice Age period. The reason that an Ice age ends, is do to a gradual warming that melts the ice(no shit sherlock-right?)-now, if there is a gradual warming trend, then the earth must be in a global warming period, and will continue to be so, untill we enter another global cooling period-leading into the next ice age.

Read this article to get some info on whats really happening:

I'm darned uncomfortable scrunched under my bed with my laptop. I rarely go out, because I'm afraid.
We are doomed.
I know that's true because David Suzuki and Al Gore say so. Every natural aberration, whether it be a bush fire in Australia, the recent once in-a-decade blizzard in Saskatchewan or a Typhoon in China, is attributed to climate change for which we energy pigs are to blame.
For almost 20 years I have watched, with fascination and disgust, while the theory of human-induced climate change evolved from an interesting scientific hypothesis to widely accepted dogma.
The idea is, by its very nature, not provable. Instead, increasingly powerful computers have been feed questionable data to calculate meaningless projections with excruciating accuracy.
Moonshine in; moonshine out. That's high-tech astrology, not science.
Predictions aren't facts, but thanks to the greatest public relations triumph in modern times, the general public believes they are.
A recent Globe and Mail poll revealed that 52 percent of Canadians regard human-induced global warming, as "life threatening". What was once a small cult of true believers has become a major apocalyptic religion.
However, there's a disconnect. Only 20 percent would consider parking their cars and taking public transit to work.
The evangelical campaign, led by well-heeled environmental lobbies like Greenpeace and high powered public relations firms like Vancouver-based James Hoggan and Associates, tends to focus on slagging the credentials, motives, and competence of scientists who reject the doomsday predictions.
Even eminent scholars like Richard Lindzen of MIT and Patrick Michaels of the University of Virginia are mocked.
Another tactic is to bombard the media with spurious testimony that "the Earth is in trouble". The flavour of the month is that melting Greenland and Antarctic ice caps will cause the sea levels to rise and swamp coastal settlements.
According to the Danish Meteorological Institute, Greenland's average temperature has actually dropped 1 degree Celsius since the 1940'ies.
Within the last two years, five studies have shown that, while the ice cap is shrinking around its margins, increased snowfall is thickening it at higher elevations.
Two studies show a small net annual loss of ice and two show a small net gain. One reports a net loss of 240 cubic kilometres per year, which sounds like a lot but is inconsequential relative to the total volume of ice.
Of the five estimates, it was the only one that I’ve seen publicized.
Similarly, the edge of the Antarctic cap is thinning, but in the continental interior, which has been cooling, the ice is thickening. Moreover, the highly publicized disintegration of the Larsen Ice Shelf in 2002 didn't raise sea level by even a millimetre because ice shelves are, by definition, floating in the water. When they melt, the water level remains constant.(*P-Dub editorial note: Think displacement-drop an ice cube into a glass of water, watch the level of the water rise, as the ice's weight causes 95% submersion. Let the ice melt, and the water line might even lower in the glass-not due to evaporation-but because when water freezes, it expands, so this means that when it melts there will be less than when it was ice.)
A few global warming enthusiasts blamed the 2005 hurricane Katrina disaster on human-induced climate change rather than on the human stupidity of building half of a city below sea level, behind inadequate dike.
There were dire predictions that the 2006 hurricane season would be horrendous but, when it turned out to be one of the least turbulent in decades, very little was said.
Alternative theories that most climate change is caused by solar activity or changes in the earth's orbit can't be proved anymore than human-induced change can be, but they are more reasonably based.
Climate has always sea-sawed radically, even within the span of human history, but long before SUVs and coal-fired power plants.
Carbon dioxide emissions may have some climatic influence, but not enough to justify wrecking the developed worlds economy to reduce them.
Unfortunately, the Intergovernmental Panel on Climate Change is a typical United Nations bureaucracy, locked in inertia and unable to seriously consider any mechanism other than human-induced greenhouse gases as the principal cause of climate change.
The IPCC, created in 1988 has about 2,500 members. They review and condense published work. Few participate in preparing final reports and fewer still in writing the political summaries, in which governments, and even environmental groups are represented.
Professor Lindzen, who participated in the 2001 panel, says, "consensus was reached before the research had even begun."
Stephen Schneider, one of the more colourful senior members of the IPCC, was quoted several years ago in Discovery as saying: "We need to get some broad- based support, to capture the publics imagination...getting loads of media coverage...we have to offer up scary scenarios, make simplified, dramatic statements."
The ranting of a maverick? Well, how about this from Sir John Houghton, first chair of the IPCC: "Unless we announce disasters no one will listen."
Scientific objectivity at its best.

Good read, I believe global warming to be true, ask any older person (older than 50), and they will tell you that the sun is a lot fucking harsher then it was when they were kids.

I dont believe global warming is caused by humans at all man.. Its just the huge cycle that happends time by time. Once the warming is over were all dead and the ice age is on its way. And the big cycle starts again untill there is no earth left.

Actually its got to do with the magnetic fields switching upside down. The serval years that take it to switch cause the warming and cooling.

thats exactly what i believe and it's what all my science and biology teachers tell us too
its a bunch of BS that it was caused by humans and all these pollutants and whatever
and on that note Al Gore is a douche bag, he is not a scientist HE'S AN EX VICE PRESIDENT
he doesnt do all that research he jus takes it from other scientists and turns it into his own words and makes little charts and all that

In the past 60 years we (as in humans) have consumed more of of the earths resources (food, oil, waste) than in the all of time humans have inhabited the earth, realistically one cant really say that is a natural cycle because humans have done more since the indutrial age than in any other time so how can one say that this is a natural cycle, we created a hole in the ozone that people thought wasn't true but it is, everywhere else in the world people get the idea behind it...just not in north America ...this is just my opinion....but i don't think so many big people would be on this if it was just an idea....
